摘要：	Across the USA, there has been interest among the State DOTs to investigate alternative technologies to estimate travel time such as the use of cell phones as travel probes. The project was initiated by the Florida Department of Transportation (FDOT) at Florida International University (FIU) in September 2004. The report summaries the studies and investigations regarding the maturity of cell phone technologies for application as real-time traffic probes for travel time estimations along the highways and roadways. Also, the reliability, accuracy, and reproducibility of the travel speed and travel time computations based upon the cell phones as travel probes have been investigated and compared with other methods such as the 511-based operations and global Positioning System (GPS) - based measurements. / NOTE: Final rept.
